How to convert Object in Array

I have a object and I can try to convert this object in a special array,

This is the index
const index = 3

This is my object
object = { fruit: apple vegetable: carrot number: 5 color: red }

This is the array structure that I want to achieve
[ 3: { fruit: apple vegetable: carrot number: 5 color: red } ]

I´m not expert in arrays but I try this and dont´t convert in array with the special structure

this.object.entries(newObj).map(x => { return index[x] })

Please could you help me, I would really appreciate your help.

>Solution :

Generate a new array with required length and assign the object to required index

const index = 3
const myObject = { fruit: 'apple', vegetable: 'carrot', number: 5, color: 'red' }
const op = new Array(index + 1);
op[index] = myObject;
